Hollow　MoS2/g-C3N4　hybrids　were　obtained　through　a　combination　route　of　hard-templating　technique　and　impregnation-sulfidation　method.　The　physicochemical,　optical/electric　and　electrocatalytic　properties　of　the　obtained　samples　were　characterized　by　X-ray　diffraction　(XRD),　scanning　electron　microscopy　(SEM),　transmission　electron　microscopy　(TEM),　X-ray　photoelectron　spectroscopy　(XPS),　UV-vis　diffuse　reflectance　spectroscopy,　photoluminescence　(PL)　spectroscopy　and　electrochemical　measurement.　Their　photocatalytic　activities　were　evaluated　by　H2　production　from　lactic　acid　aqueous　solution　with　visible-light　irradiation.　The　results　showed　that　MoS2/HCNS　nanojunctions　exhibited　enhanced　photocatalytic　H2　production,　which　could　be　attributed　to　the　thin　layered　junctions　formed　between　MoS2　and　HCNS　for　efficient　charge　separation　and　the　active　sites　provided　by　MoS2　for　H2　production　at　lower　over　potentials.　©　2015　Elsevier　B.V.
